USA Network has announced a trio of guest stars for Psych Season 8.

KALI HAWK (New Girl) will appear on one episode as a private investigator who crosses path with Shawn and Gus.

VINNIE JONES (Elementary) will stop by as a violent British criminal whose right-hand woman is portrayed by OLIVIA D'ABO (The Wonder Years).

The three newcomers will join two returning favorites on the series, as Cary Elwes will reprise the role of Despereaux, while Kristy Swanson will be seen again as Marlowe.

USA is yet to reveal a premiere date for new episodes.
